Winchester area received rain from a thunderstorm last night around 7:30PM.  An estimated leaf wetness period is 14.5 hours with an average temperature of 63F.  It was a risk event for Phomopsis, black rot, downy mildew, and Botrytis.

Our Chardonnay is in full bloom and Merlot is about 60-70% bloom now.  Hopefully this weather won’t affect fruit set.
